Mr. duggar, a senior citizen, can easily recall the first car he purchased, but cannot remember the name of the current secretary of state. mr. duggar's memory is far better than his memory.

The correct answer is: Mr. Duggar's episodic memory is far better than his semantic memory.

Answer 1: Episodic memory refers to a person's long-term memory about events and experiences that have occurred in his or her life. Just like all of us have unique experiences and events that occur in our lives, we all have unique and personal episodic memories. An example of an episodic memory is remembering the experience of your high school graduation day or vividly remembering your wedding day. 

Answer 2: Semantic memory refers to a type of long-term memory about things that we have not personally experienced. Semantic memory involves common and general knowledge/ facts. Examples of semantic memory are knowing the name of the first US President, the year World War II started, the colors of the rainbow, the planets of the solar system, etc. Since Mr. Duggar cannot remember  the name of the current secretary of state, his semantic memory is worse compared to his episodic memory.
